Sky-Watcher Quattro 150P

The Sky-Watcher Quattro 150P f/4 Imaging Newtonian with Aplanatic Super Coma Corrector offers a fast f/4 focal ratio which has been specially designed for high quality astrophotography with short exposure times. It also does double duty as a fine telescope for visual observations. It is supplied complete with its own optically matched M48 Aplanatic Super Coma Corrector comprising four lens elements including one ED element.

Sky-Watcher Quattro 150PThe Sky-Watcher Quattro 150P imaging Newtonian is an affordable, large aperture astrograph, ideal for users searching for a fast-imaging system that will work for both astrophotography and visual astronomy. With its swift f/4 focal ratio, this astrograph can produce an exposure 6x faster than the average 8-inch f/10 Schmidt Cassegrain telescope (or 8.4x faster with the included coma corrector/reducer). Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy.

The Sky-Watcher Quattro 150P utilizes the same Linear Power Focuser as the other models in the Quattro range, which incorporates four precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. Moving the drawtube by the roller rather than a rack and pinion ensures exceptionally smooth operation, great feel and precise adjustability. The dual-speed feature has a second focus knob that has a 10:1 speed reduction to provide the super-fine adjustments even the most demanding users can appreciate.

Like all Sky-Watcher reflectors, the Quattro Imaging Newtonian features borosilicate mirrors coated with Sky-Watcher’s proprietary Radiant Aluminum Quartz (RAQ) coatings, producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watcher’s signature glossy finish. The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an included Aplanatic Super Coma Corrector, offering a perfectly matched coma corrector/reducer for those who want to take their imaging to the next level.

Included with the Sky-Watcher Quattro 150P are 1.25 and 2-inch eyepiece adapters, a 6×30 finderscope, tube rings, V-style dovetail plate, and a 70° Ultra-Wide 22mm eyepiece.
